Detailed Description

Bosch 53011445 is a conventional front brake rotor engineered for direct replacement service on the front axle of the Lincoln Aviator and Ford Explorer. The vented iron alloy design helps manage brake heat during repeated stops, while the smooth directional surface supports even pad engagement. With a coated hat, rust-resistant coating, and Geomet disc finish, this rotor is built for drivers replacing worn or warped front rotors on 2020-2025 Lincoln Aviator and 2020-2023 Ford Explorer vehicles.

This part cross-references Ford/Lincoln OE part number L1MZ1125A for the same application.

Common Reasons for Replacement

• Brake pulsation or steering wheel shake during braking
• Rotor scoring, grooves, or uneven wear
• Corrosion on the braking surface or hat area
• Reduced braking smoothness from thickness variation
• Noise caused by worn front rotors

Installation Notes and Tips

Verify front axle fitment before installation and confirm rotor dimensions against the original part. Clean the hub mounting surface thoroughly, inspect pads and caliper hardware, and measure rotor thickness after installation to confirm service limits are met. For best results, replace rotors in axle pairs and bed in new pads according to the pad manufacturer’s procedure.

Quality Assurance

Bosch QuietCast brake components are built to OE-style standards for fit, finish, and corrosion protection. This rotor is a rotor without hub assembly and does not include bearings.
